Hybrid lighting controls
Lighting enhances the visibility of outdoor
signages, which should be switched ON once
it becomes dark and depending on the need,
they must be allowed to glow for the entire
night or for a few hours. Hyderabad based
Kakatiya Energy Systems offers SWADEEP 02
EC for hoardings and SIGN SWITCH for
signages. These products offer a combination
of light and duration sensing. These products
have greatly simplified the entire task of
automation by adopting an advanced
electronic design with all protective features
and do not need any clock settings or clock
corrections.
A range of models using this state-of-the-art
micro controller based technology for various
loads have been developed to suit the field
requirements. These include SWADEEP 02
EC for hoardings and SIGN SWITCH for
signages. These devices are not mere
automatic switches but also offer extra
protective features like auto over voltage trip
and auto reset. They are designed to switch
ON only after sunset when the natural light
level falls below 60 lux. They offer a provision
for switch OFF at sunrise or after expiry of
duration. The products are meant for direct
mounting in the outdoors and conform to IP54
and they are immune to artificial lights, dust,
cloud, rain, humidity, fog, mist etc.
SIGN SWITCH is a product that can eliminate
all the woes related to signage switching
automation. This engineering marvel is
unique and has the potential of providing
maximum visibility to the signage, while
conserving energy. The user can select the
ON duration for the signage after sunset.
Even the light level for switching ON can also
be selected by the user. A host of other
features bundled into the product include its
capability to switch a load of upto 50 tube
lights (3kW), memory back up for power
interruptions, immunity to dust, cloud cover,
bird sittings and artificial sources of light. The
product does not call for any additional
accessories and so no hidden costs. This
switch is designed to be an integral part of
the signage. It can be installed at the time of
manufacturing the signage itself. It comes with
FR & UV stabilized container to withstand
tropical weather conditions. It has built-in by
pass arrangement for day time checking and
signage maintenance.
On the other hand, SWADEEP 02 EC works
on solar radiation and is controlled by a
microprocessor based digital clock. It is
designed to understand the sunlight and
switch ON when light level drops below 60
lux and switch OFF when light level goes
above 10 lux. The device offers a provision
for switching OFF after expiry of duration
from 4-8 hours with half hourly steps. The
system is provided with memory backup
during power interruptions. It has by pass
arrangement for day time checking and
comes with FR & UV stabilized body to
withstand the tough outdoor weather
conditions. They come in six models,
convenient for single (three models: 3, 5 &
8kW) and three phase (three models: 5, 8 &
12kW) loads. These models come as outdoor
mountable enclosure with all the needed
accessories like mounting brackets, cable
glands, lock & key arrangement, contactor
and protective MCBs. The device has a built
in over voltage sense, trip and auto reset and
also a low voltage sense trip and auto reset.
The MCB provides for over load sense trip
and latch to provide the needed protection
from circuit faults.
Kakatiya is set to display these lighting controls
at Sign & Graphic Imaging Middle East 2007.
